LS-546-1 Heat Sealing Tester

Use

Heat Seal Tester is based on the heat sealing method, and is professionally applicable to the determination of heat seal temperature, dwell time, and the pressure of various composite films to guide industrial production. The instrument adopts the specially designed heat sealing jaws, which completely conform to multiple national and international.

Character

7 inch HD LCD touch screen, more intuitive content, more convenient operation

Sai Cheng independent research and development of “fixed temperature micro-control” system, temperature control accuracy is higher

Lower cylinder synchronous loop to ensure pressure balance

The aluminum potting type hot head ensures the heating uniformity of the hot surface

Upper and lower heat head independent temperature control, ultra-long hot cover design, to meet different customer needs

Manual and foot switch dual mode, humanized structure design

Anti-hot design and leakage protection design, safer operation

Micro printer for easy printing of test results

LS-546-1 Heat Sealing Tester

Principle

The sample to be sealed is placed between the upper and lower hot head by the hot pressing sealing method, and the sample is sealed under the preset temperature, pressure and time. After repeated trials to provide guidance for users to find the appropriate heat sealing parameters.

Standards

QB/T 2358, ASTM F2029, YBB 00122003

 

LS-546-1 Heat Sealing Tester

Applications Specifications

Basic Applications Films with Smooth Surface
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others. Heat sealing surface should be smooth and width can be designed based on user requirements.
 Films with Decorative Pattern Surface
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others. Heat sealing surface can be designed based on user requirements.
Extended ApplicationsCovers of Jelly Cups
The instrument is composed of the upper and lower jaws. The upper one is round-shape while the lower one is designed as a specimen mould whose size exactly fits the jelly cup. Put the jelly cup in the mould of lower jaw, and heat seal can be finished by upper jaw pushing. (Customization required)
Plastic Flexible Tubes
The ends of plastic flexible tubes are placed in between upper and lower jaws and then sealed to form a package.
